Re: Lat/Long RPGLE, and tornadoes

Douglas,

Add the following H specs:
     H ActGrp(*CALLER)
     H DftActGrp(*NO)
     H BNDDIR('QC2LE')


And then you'll have access to all of those mathematical functions.  See 
also
DSPSRVPGM SRVPGM(QC2UTIL2) DETAIL(*PROCEXP)

See section 5.1 of "Who Knew You Could Do That with RPG IV?" available 
online at 
http://www.redbooks.ibm.com/abstracts/sg245402.html

List of available functions is at
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/apis/hll3.htm

Having said all this, if you don't want to roll your own, then look at

I'm very happy with this company.  And you get monthly updates included.

"Distances can be calculated between Zip Codes or between known 
latitude/longitude coordinates. Distances are provided in statute miles, 
kilometers, and nautical miles."

Software is free with a year's prepaid subscription.
"The cost for a one-year subscription to Z4 LAT/LON is $990. The cost for 
additional years is $990 per year."
Like I said, you do get monthly updates, so it is not money being paid 
solely to pad his pockets.

ps:  I hope that you and your family came through the tornadoes ok.
